DNV launches hydrogen safety standard for scalable production

DNV, the independent energy assurance provider, has launched a new standard, DNV-ST-J301, to establish a comprehensive safety framework for electrolyser systems. This groundbreaking standard aims to support the safe and efficient production of hydrogen and its derivatives through water electrolysis, aligning with emerging global regulations and the ISO 22734 standard.

The new certification focuses on the design, construction, and operation of electrolyser systems, integrating advanced safety measures to address the risks inherent in hydrogen production. DNV-ST-J301 simplifies compliance for developers by consolidating technical safety requirements into a single document, providing clarity and cost efficiency. It also offers a lifecycle approach, ensuring that systems meet safety benchmarks from design to operation.

The initiative follows insights from a joint industry project involving 30 global partners and coincides with the EU Innovation Fund’s hydrogen auction, where adherence to standards like ISO 22734 is critical for project success.

Hydrogen is seen as pivotal in decarbonising hard-to-electrify sectors, replacing traditional fossil fuels in industries like chemicals, fertilisers, and heavy transportation. Electrolysers adhering to rigorous standards ensure the reliable and sustainable production of these clean molecules.

DNV’s complementary services, including certifications for power-to-x facilities and environmental sustainability, reinforce the new standard’s objectives. Additional documents, such as DNV-RP-J302 for electrolyser performance evaluation, will further advance safety and efficiency in hydrogen systems.

“This new standard provides a comprehensive validation framework, crucial for establishing a global electrolyser industry for renewable hydrogen,” said Magnus Killingland, global segment lead for Hydrogen and Ammonia, Energy Systems at DNV. “By enabling cost reductions through standardisation, it ensures hydrogen’s viability as a clean molecule for the hardest-to-abate sectors.”

A safer hydrogen economy

The DNV-ST-J301 standard aims to foster transparency and accountability while reducing project uncertainties. Accredited certifications provide confidence to stakeholders, ensuring compliance with regulations like the EU’s Pressure Equipment Directive.

​​“DNV is at the forefront of creating standards and certification schemes for renewable hydrogen production. These efforts are critical for enabling global decarbonization,” said Peter Paschke, global lead – power-to-x, Energy Systems at DNV. “For companies participating in the recently announced EU Innovation Fund hydrogen auction, where the ISO 22734 standard is to be complied with, such certifications will be pivotal for success.”
